Erasing A Lost Or Forgotten Password (Clearing Cmos) - IBM 8486 - eServer xSeries 100 User Manual

Administrator password
If an administrator password is set, you must type the administrator password for
access to the full Configuration/Setup Utility menu. You can use any combination of
up to seven characters (A–Z, a–z, and 0–9) for the password. The Administrator
Password choice is on the Configuration/Setup Utility menu only if an optional IBM
Remote Supervisor Adapter II is installed.
Resetting passwords
If you forget the power-on or administrator password, you can change the pin
position of the clear CMOS jumper on the system board to bypass the power-on or
administrator password check. This enables you to reset these passwords.

6. Move the CMOS recovery jumper from pins 1 and 2 to pins 2 and 3.
7. Wait 60 seconds; then, return the CMOS recovery jumper to pins 1 and 2.
8. Replace any adapters that were removed; then, replace the side cover (see
"Installing the side cover" on page 35).
You can now start the server one time without having to use the user
password and start the Configuration/Setup Utility program. At this time, you
can either delete the old password or set a new user password. If you do not
change or delete the password, the next time you start the server the original
user password will be reinstated.
